We conduct a two-tailed test at the .05 significance level with data that afford 8 degrees of freedom. When we look up the critical value of t, we will expect it to be ____________ the corresponding critical value of z.
A) substantially larger than
B) the same as
C) slightly smaller than
D) either larger than or smaller than, depending on n
